在Swift的didSelectRowATIndexPath中调用DatePicker

Question

DatePicker如何在TableView中单击特定单元格。此外，我还需要一个完成按钮，以便在使用

Answer 1

在你的TableViewController:

        var chosenNumber = 0
        override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
            //set your chosenNumber here based on your the cell that was clicked
           chosenNumber = 1
        }
         override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject!) {
            let controller = segue.destinationViewController as! ViewController
            //the startRow variable in the ViewController with the picker is set to the same value as the chosenNumber
            controller.startRow = chosenNumber
        }

在你的ViewController中使用picker:

        var startRow = 0
        override func viewDidLoad() {
            //the selected item in the spinner will the value of startRow
            spinner.selectRow(startRow, inComponent: 0, animated: false)
        }

当按钮被点击时隐藏旋转器:

        @IBAction func buttonClicked(sender: UIButton) {
             spinner.hidden = true
        }
